Making H2while the sun shines: Recently, an inorganic catalyst based on Co2+ and phosphate ions was developed that operates in neutral water under ambient conditions to produce O2 from H2O at low overpotentials. Coupling the setup to a counter electrode at which H2 formation takes place as well as to a solar cell could lead to solar water splitting into H2 and O2.
